- a conductor with wire winding in a slot of a laminated core of a stator;
- wherein the wire winding is embedded in an encapsulation;
- and
- the encapsulation includes volume-increasing particles.
1 more element
A method for producing an electrical insulation system for an electric motor, the method comprising:
- forming a conductor from winding wire and a carrier medium loaded with filled impregnating resin;
- drawing the formed conductor into the slots of a laminated core of a stator of the electric motor;
- heating the laminated core such that gas-filled particles present in the impregnating resin expand with an increase in volume and thereby increase the volume of the not yet cured impregnating resin;
- and
- curing the impregnated winding wire carrier insulation.
